Connect SolisCloud in about a minute

For most supported Solis homes, the quickest way to connect a hybrid inverter to 1app.energy is now SolisCloud sign-in.

Open Settings → Devices in 1app.energy, choose Solis, select Sign in with SolisCloud, and approve access with the SolisCloud account that owns the plant. If SolisCloud returns more than one inverter, 1app.energy will ask you to choose the correct one before marking the device connected.

That means new customers should not normally need to request an API key, wait for API activation, or copy a Key ID and Secret just to get started.

Once the inverter is verified, 1app.energy can give the customer one app for live solar, battery, grid, tariff and EV context where supported, instead of leaving them to jump between device apps and API settings.

The API-key route is still useful as a manual fallback for existing homes, support-led setup, or SolisCloud accounts where sign-in is not available. This guide explains the quick sign-in route first, then the fallback.

The quick route: SolisCloud sign-in

1. In 1app.energy, go to Settings → Devices.
2. Choose Solis.
3. Click Sign in with SolisCloud.
4. Sign in with the SolisCloud account that owns the plant.
5. Select the correct inverter if 1app.energy asks you to choose one.

Once the backend verifies the inverter, your Solis device can supply supported inverter, battery, solar and grid data to the dashboard. Where supported and customer-enabled, the same Solis connection can also support tariff-aware battery behaviour.

When to use API-key fallback

Use the manual API-key setup only if:

• SolisCloud sign-in is not shown in 1app.energy;
• 1app.energy support asks you to use the fallback route;
• you already have an API-key connection and want to reconnect it manually;
• your SolisCloud account cannot complete the sign-in flow.

For API-key fallback, 1app.energy needs two values from SolisCloud:

1. Your API Key ID (a long number, usually starting 1300...)
2. Your API Key Secret

Unlike Octopus or myenergi, Solis does not generate these instantly. You first have to request API access from Solis support — it usually comes through within 24–48 hours. Once approved, you generate the key in two clicks.

Why 1app.energy needs SolisCloud access

1app.energy uses your SolisCloud connection to read supported inverter data such as solar generation, battery state of charge, and grid import/export. That is what powers the energy flow on your dashboard and, where supported and customer-enabled, can help make battery behaviour more tariff-aware alongside EV charging context.

If you connect with SolisCloud sign-in, SolisCloud handles the authorisation. If you use API-key fallback, the Key Secret behaves like a password — we store it encrypted and only use it to talk to SolisCloud on your behalf.

Before you use API-key fallback

• Use the SolisCloud account that owns the plant (the email your installer used to register your inverter, or your own if you registered it yourself).
• You will need access to the email address linked to that account — Solis sends a verification code there every time you view the key.
• Note that Solis state API access is "only available to organisation leaders" of a plant. If your installer registered the plant under their account and never transferred ownership to you, you will need to ask them to either transfer it or generate the key for you.

Manual fallback phase 1 — Request API access (one-time)

If you have never used the SolisCloud API before, your API Management page will show a Nonactivated badge. You need to submit a one-time request before you can generate a key.

Step 1 — Log in to SolisCloud

Go to soliscloud.com and sign in with the email and password for your plant.

Step 2 — Open Basic Settings

Click the avatar icon in the top-right corner. From the dropdown, choose Basic Settings.

Step 3 — Go to API Management

In the left-hand Mine sidebar, click API Management.

You will see the SolisCloud Plant Monitoring API panel. If it shows the Nonactivated badge, click the orange Activate now button.

Step 4 — Submit the API access ticket

A support ticket form opens. Fill it in like this:

• Product Type: Monitoring Platform
• Product Name: Solis Cloud
• Country: your country
• Tickets Type: API Access Request
• API Account Email Address: the email you logged in with

Battery Brand can be left blank or filled in if you know it.

If the form has a free-text Description or Message field (it sometimes does, depending on the SolisCloud version), copy and paste the template below — just fill in the bracketed bits before sending:

Subject: API Access Request — SolisCloud Plant Monitoring API

Hello SolisCloud Support,

Please could you enable API access on my SolisCloud account so I can
generate an API Key ID and Secret from API Management?

I would like to use it with 1app.energy to get more out of my Solis
inverter at home.

Account details:
- SolisCloud login email: [your account email]
- Plant name: [your plant name]
- Inverter serial number: [your inverter SN]
- Country: [your country]

Thank you,
[Your name]

You can find your inverter serial number on the side of the inverter itself, or under Plant Overview → Devices in SolisCloud.

Submit the ticket. Solis support typically approves within one to two working days. You will receive an email when access is granted.

Tip: While you wait, you can still complete the rest of your 1app.energy onboarding. For most homes, try SolisCloud sign-in first and use this fallback only if needed.

Manual fallback phase 2 — Retrieve your API key

Once Solis emails you to confirm approval, the API Management panel switches from Nonactivated to Activated, and a View Key button appears.

Step 5 — Open the Service menu

From the SolisCloud home (Plant Overview), look at the dark sidebar on the left. Click the Service icon at the bottom (the four-petal flower).

Step 6 — Open API Management again

In the Service submenu, click API Management.

The panel now shows Activated in green, with two buttons: View Key and Disable.

Click View Key.

Step 7 — Verify by email

For security, Solis emails a verification code to the address linked to your account every time you view the key.

In the Email Authentication dialog, click the orange Verification code button. Check your inbox, copy the 6-digit code into the box, and click Confirm.

Step 8 — Copy the Key ID and Key Secret

After verification, the View API Key dialog opens, showing your API ID, API Secret, and an API URL.

Use the Copy button next to each value. You only need the API ID and API Secret for 1app.energy — the API URL is built in.

The API ID is a long number (often starting with 1300). The Secret is a longer alphanumeric string starting with something like b60....

Step 9 — Use API-key fallback in 1app.energy

In 1app.energy, go to Settings → Devices, choose Solis, then choose Use API key instead. Paste in:

• The API Key ID as API Key ID
• The API Key Secret as API Key Secret

Then click Find plants. We call SolisCloud, list every plant linked to those credentials, and ask you to pick the one you want to connect. Most homeowners only have one plant, in which case it is auto-selected.

Once you confirm the plant, your inverter, battery, and solar generation will appear on your dashboard after the connection is verified and the next sync completes. SolisCloud timing can vary, so live or recent data may take a little longer to settle.

If something goes wrong

• "Activate now" not visible — you are not the organisation leader for the plant. Ask whoever registered the plant (often your installer) to either transfer ownership or generate the key on your behalf.
• SolisCloud sign-in is not available — use the API-key fallback above, or email support if the app did not show the sign-in option when you chose Solis.
• Ticket rejected or no email after 48 hours — reply to the ticket from the same email account, confirming the email address matches your SolisCloud login. Solis sometimes need this to match before they approve.
• Verification code never arrives — check spam, then confirm the email shown in the dialog (e.g. 731***280@qq.com) matches an inbox you can access. If it does not, your account is registered against an old email and Solis support will need to update it.
• "Find plants" returns nothing in 1app.energy — the credentials are valid but the API user has no plants linked. Most often this means your installer activated API access against their own account, not yours. Ask them to grant you access or generate the key from your account instead.
• Find plants returns the wrong plant — pick the right one from the dropdown. We resolve the inverter automatically from the chosen plant.

A note on safety

Your Key Secret gives read access to all plants linked to your SolisCloud account. Treat it like a password:

• Do not paste it into chat with strangers, screenshots, or public forums.
• If you ever suspect it has leaked, click Disable in SolisCloud's API Management page to revoke it, then submit a fresh API access ticket and re-enter the new credentials in 1app.energy.

We never share your key with third parties.
